Rustdoc-Json should say if an item in stable or not (for items in the standard library).
It should model all the ways an item can be (un)stable, like const stability and body-instability.
This is motivated by cargo-semver-checks wanting to work on the standard library, but that requires being able to filter out breaking changes to unstable items, so it can only flag breaking changes to stable items. This in turn is motivated by
#153486.
An abandoned implementation of this existed at #154603.
